An educational or social factor that I think really influences the performance of children in school is their environment at home. Lack of parenting at home can really hurt a child's performance in school, because if they don't have the motivation to do anything at home and don't have good role models, then they're going to think that they never have to do anything. Parents who are really involved in their child's education and learning process tend to bring up children who get good grades and are well behaved. It's important for children to have good role models at home so they are constantly reminded of how to behave. Children who don't have involved parents tend to lack motivation and don't do as well in school.
